Summary: Mobile-edge computing (MEC) and intelligent reflecting surface (IRS) are two promising technologies for massive connectivity in future IoT networks. MEC allows IoT devices (IDs) to offload computation tasks and extend their lifespan, while IRS enhances the channel condition between IDs and access points (APs) within the MEC system. The article applies IRS in a multi-ID MEC system to improve latency performance through a hybrid multiple access scheme and a timing protocol for the IDs. It also tackles the latency optimization problem with joint optimization of power allocation, IRS phase shift matrix, and uplink/downlink beamforming under maximum power constraint.
